Yesterday I was checking to see if any of my 10 orchids needed watering and noticed (1) aphids on one of the dendrobiums and (2) spidery webs (from mites?) on the backs of some leaves on my brassia. Worse though, was trying to pick off an aphid with a Q-tip soaked in alcohol and picking up a tiny little worm stuck in the crevice of a leaf node on a cattleya. I hadn't even seen it! It was light brown and segmented. I didn't think to photograph it. Any ideas on what this might be? This is my most perfect orchid in that it doesn't have any blemished leaves! I'll be ever so vigilant from now on.
